Here, in the case of calculating the change over time in the environmental conditions at the installation location of the outdoor unit based on the operating conditions of the outdoor unit as described above, the change from the outdoor unit set as one of the operating conditions of the outdoor unit is performed. The exhaust gas temperature changes depending on the intake air temperature of the air sucked into the outdoor unit as described above.When the outdoor unit is operated, this intake temperature matches the outside air temperature around the outdoor unit, that is, the air temperature. The ambient environmental conditions change with the operation of the machine, which changes the intake air temperature of the air taken into the outdoor unit, and therefore, in this embodiment, when the minute time obtained by the above calculation has elapsed Obtain the intake air temperature in the outdoor unit from the temperature around the outdoor unit, calculate the exhaust gas temperature in the outdoor unit as described above based on this intake air temperature, and calculate the exhaust gas temperature thus calculated. It was set as the operating conditions of the next above the outdoor unit.

Next, in this embodiment, a method for calculating the change with time of the environmental conditions at the place where the outdoor unit is installed will be concretely described with reference to the flowcharts shown in FIGS.

First, the state of the installation site where the outdoor unit is installed,
For example, as shown in FIG. 1, when the outdoor unit 1 is installed on the veranda 11 on each floor of the building 10, the condition at the installation location, particularly obstacles such as other buildings adjacent to this installation location. The state of the analysis field is determined in consideration of the distance L up to 10, and a grid is formed corresponding to each area in order to investigate changes in environmental conditions such as temperature, wind speed, and atmospheric pressure in each area of the analysis field. (S1).

Next, the installation environment conditions such as temperature, natural wind condition and atmospheric pressure at the installation location of the outdoor unit are set as initial values (S2), and the variables such as temperature, wind speed and pressure in the above-mentioned analysis field are set. The initial distribution is input, and a convergence determination value for determining whether or not changes in environmental conditions such as temperature, wind speed, and atmospheric pressure in the analysis field have converged is set (S3).

Then, the calculation for obtaining the environmental condition when the time interval Δt advances is started (S4), and the operation of the exhaust speed, the intake speed of the outdoor unit to be used, the exhaust temperature of the air discharged from the outdoor unit, etc. is started. Set the condition (S
5).

Next, calculation is carried out based on the equations for conservation of mass, momentum, and energy and the equations for turbulent energy and turbulent flow rate shown in (Equation 2) to (Equation 4) (S6),
For each region set by the grid, the time interval Δt
When the temperature has passed, conditions such as temperature, wind speed, and atmospheric pressure are calculated to calculate changes in environmental conditions in each region, and the results are compared with the above convergence determination value to determine convergence (S
6).

When the change in the environmental condition has not converged, the process returns to the step (S4), and the calculation for obtaining the environmental condition when the time interval Δt advances again is started and converged. Repeat the above operation until
When converged, this result is output (S7), and the operation ends.

When the operating condition of the outdoor unit is set in the above (S5), the exhaust gas temperature which is one of the conditions, the exhaust gas temperature Tout and the intake air temperature T are as described above.
The temperature difference ΔT with in is obtained by the above (Formula 1), and this temperature difference ΔT is added to the intake air temperature Tin in the outdoor unit to obtain the exhaust temperature Tout, but the outdoor unit is operated as described above. When the environmental conditions change, the intake air temperature Tin sucked into the outdoor unit changes accordingly. Therefore, in this embodiment, the exhaust temperature from the outdoor unit is calculated as shown in the flowchart of FIG. Was set as the operating condition.

First, as data, the exhaust gas temperature Tout and the intake air temperature Tin obtained based on the operating performance of the outdoor unit used.
And the temperature set in the installation environment conditions, that is, the outside air temperature T _0, is read (S50), and it is determined whether the number of calculations N in (S4) above is the first time (N = 1). (S51).

When the number of calculations N is 1, the intake air temperature Tin sucked into the outdoor unit is the outside air temperature T _0.
And the outside air temperature T ₀ read as described above.
The temperature difference ΔT is added to the above to obtain the exhaust temperature Tout (S
52), the exhaust temperature Tout is input as the operating condition of the outdoor unit.

On the other hand, when the number of calculations N is other than 1, the temperature of the air in the suction part of the outdoor unit is calculated from the result of the change in the environmental conditions obtained by the calculation in (S6) above, and this is taken in. The temperature Tin is set (S53), the temperature difference ΔT is added to the intake air temperature Tin to obtain the exhaust temperature Tout (S54), and the exhaust temperature Tout is input as the operating condition of the outdoor unit.

As described above, based on the change in the intake air temperature Tin in the outdoor unit, the exhaust temperature T under the operating conditions of the outdoor unit
By changing out and inputting it, it has become possible to more accurately calculate the changes over time in the environmental conditions at the location where the outdoor unit is installed, especially over time.

Next, as shown in FIG. 1, a veranda 11 on each floor of the building 10 having an obstacle 20 such as another building adjacent thereto.
Assuming that the outdoor unit 1 is installed in the outdoor unit 1, the change over time in the environmental conditions in the place where the outdoor unit 1 is installed is calculated as described above, and the horsepower of the outdoor unit 1 to be used and the installation place of the outdoor unit 1 are used. The relationship between the distance L from the obstacle 20 to the obstacle 20 and the floor number of the building 10 in which the outdoor unit 1 is installed is obtained, and the horsepower number of the outdoor unit suitable for the floor number of the building 10 in which the outdoor unit 1 is installed is obtained. did.

Here, in obtaining the above relationship, as the installation environmental condition at the place where the outdoor unit is installed, the temperature is set to 35 ° C. in the case of summer when the cooling capacity of the outdoor unit is largely reduced, In addition, the wind speed of natural wind is set to 0 m / s and the pressure is set to the normal atmospheric pressure, while the outdoor unit has a horsepower number, a rated air volume, a cooling capacity, an exhaust speed, and an intake speed as shown in Table 1 below. The types of outdoor units A to C were used.

[0042]

[Table 1]

First, assuming the case where the outdoor unit B of 40 horsepower is installed, the distance L to the obstacle is set to 3 m, 5 m, 10 m,
In the case of 20 m, the rise of the intake air temperature in each outdoor unit B installed on each floor was calculated by the calculation based on the flow chart shown in FIG. 2, and the result is shown in FIG. In the figure, the result when the distance L to the obstacle is 3 m is ●, and the result when it is 5 m is ▲
The results in the case of 10 m are shown by ▪, and the results in the case of 20 m are shown by ×.

As a result, the intake air temperature rises as the number of floors of the building in which the outdoor unit is installed rises, and in particular, the closer the distance L to the obstacle is, the more severe the intake air temperature rises. The same phenomenon occurs when the outdoor unit A of 24 horsepower and the outdoor unit C of 60 horsepower are used, and the intake air temperature in the outdoor unit rises as the horsepower of the outdoor unit increases.

Next, when the distance L to the obstacle is set to 3 m and the above outdoor units A to C are installed on the respective floors, the intake air temperature rises in the outdoor units A to C installed on the respective floors. Was calculated by the calculation based on the flow chart shown in FIG. 2, and the result is shown in FIG. In the figure, the result when using the outdoor unit A of 24 horsepower is ●, the result when using the outdoor unit B of 40 horsepower is ▲, and the result when using the outdoor unit C of 60 horsepower The results are shown by ■.

As a result, the higher the horsepower number of the outdoor unit used, the greater the rise in the intake air temperature in the outdoor unit. Especially, the higher the floor number of the building in which the outdoor unit is installed, the sharper the intake air temperature. The distance L to the obstacle
The same phenomenon occurs when the value is changed, and the increase in intake air temperature decreases as the distance L to the obstacle increases.

Next, the influence on the operating performance of each outdoor unit and the electric power input to each outdoor unit when the intake air temperature in each outdoor unit rises is investigated, and the rise of the intake temperature in the outdoor unit and the performance of the outdoor unit are examined. Was obtained and the result is shown in FIG.

As a result, when the intake air temperature in the outdoor unit rises, the performance of the outdoor unit gradually decreases, and as shown in FIG. 6, when the intake air temperature rises by 8 ° C., the performance of the outdoor unit becomes 85%. It became below.

Therefore, in this embodiment, in order to reduce the deterioration of the capacity of the outdoor unit, the limit temperature at which the intake air temperature rises is set to an appropriate temperature, for example, about 3 to 6 ° C. When the intake air temperature in the outdoor units A to C rises to this temperature, it is determined by the relationship between the floor number of the building in which the outdoor unit is installed and the distance L to an obstacle such as an adjacent building, and the result is shown in FIG. It was

Then, in this embodiment, based on the result shown in FIG. 7 above, the installation location is determined from the floor number of the building in which the outdoor unit is installed and the distance L to an obstacle such as an adjacent building. We decided to determine the type of outdoor unit that is suitable.

For example, the distance L to an adjacent obstacle is 1
When deciding the outdoor unit to be installed on each floor of the building with the fixed value of 0 m, if the number of floors of the building in which the outdoor unit is installed is up to the third floor, the intake temperature of the outdoor unit C of 60 hp is Since the rise in temperature does not reach the specified temperature, this outdoor unit C
However, if the number of floors of the building exceeds that, the intake air temperature rises above a predetermined temperature in the outdoor unit C of 60 horsepower, so 40 horsepower or 24 horsepower with a lower horsepower number is used. If the outdoor units B and C of horsepower are used and the number of floors of the building is up to the 8th floor, even if the outdoor unit B of 40 horsepower does not reach the predetermined temperature, the intake air temperature does not reach the predetermined temperature. The machine B can be used, but if the number of floors of the building becomes more than that, since the rise of the intake air temperature of the 40-hp outdoor unit B exceeds a predetermined temperature, it is recommended to use the 24-hp outdoor unit. To

Further, even when the outdoor unit to be installed on each floor of the building is determined when it is decided that the outdoor unit will be installed in the building on the 10th floor, for example, in the outdoor unit C of 60 horsepower, an adjacent obstacle Even if the distance to the object is 20 m or more, the rise in the intake air temperature exceeds the predetermined temperature, so the outdoor unit C of 60 hp cannot be used, and the number of horsepower is smaller than this. If the outdoor units B and C of 40 hp or 24 hp are used and the distance to the obstacle is about 10 m, the rise of the intake air temperature of the outdoor unit B of 40 hp does not reach the predetermined temperature. Therefore, this outdoor unit B can be used, but if the distance to the obstacle becomes even shorter, for example, 8 m, the rise of the intake air temperature will exceed the predetermined temperature even with this 40 Hp outdoor unit B. For 24 horses So that use of the outdoor unit.

When the type of the outdoor unit in the air conditioner installed in the building or the like is determined as described above, as in the conventional case,
It becomes possible to easily and properly determine the outdoor unit suitable for each installation location without actually conducting experiments by installing various types of outdoor units at each installation location, and before building a building. Even in the design stage, etc., it has become possible to determine in advance the appropriate type of outdoor unit to be used at each installation location.

[0054]

As described in detail above, in the method for determining the installation standard of the outdoor unit in the air conditioner according to the present invention,
Considering the installation environment conditions such as temperature, natural wind condition, distance to adjacent obstacles, etc. at the place where the outdoor unit is installed, and the operating conditions of the outdoor unit, various outdoor units are actually installed in various places. It became possible to determine the outdoor unit suitable for each installation location by performing a simulation corresponding to the case of installation.

As a result, according to the method for determining the installation standard of the outdoor unit in the air conditioner according to the present invention, various types of outdoor units are not actually installed in the respective installation locations as in the prior art, and an experiment is not performed. It will be possible to easily determine the outdoor unit suitable for each installation location, the time and cost required to determine the outdoor unit according to the installation location will be less, and the design before building the building Even in stages, it is possible to determine in advance the type of outdoor unit that will be used at each installation location, calculate the cost required for building the building in advance, and design the outdoor unit in consideration of the outdoor unit. Can be done easily.
